We wrote these practice questions from the facts in the South Dakota Driver's License Manual (Driver's License Manual (English), South Dakota Department of Public Safety, Driver Licensing Program; 72 PDF pages, the last page says 'REVISED 11/2024' (PDF file metadata: created 2025-12-02, modified 2026-06-30); linked as 'Driver's License Manual - English' on the DPS page South Dakota Driver License and Motorcycle Manuals (https://www.sd.gov/dps?id=kb_article_view&sysparm_article=KB0043733), read 2026-11-10. Page numbers cited are PDF pages, which equal the printed page numbers. PDF pp. 15-16 (blood stem cell and organ donor pages) and 69-70 (office lists) were not used. The manual has no speed-limit, insurance-minimum or crash-reporting-threshold sections, so those rules come from South Dakota Codified Laws read on sdlegislature.gov on 2026-11-10 (Titles 22, 32, 35 and ARSD 61:06:01:06); the section lists showed no amendment after SL 2025. Handbook statements that differ from or go beyond current law and how they were handled: (1) rural-highway parking (PDF p. 43: 15 feet of road width, visible 500 feet) differs from SDCL 32-30-2 (20 feet clear width, clear view from 200 feet); not tested, and the owner may want to note it; (2) first-offense DWI penalty text (PDF p. 20: fine $300-$1,000, 15-365 days in jail, license loss 90-365 days) differs from SDCL 32-23-2 (Class 1 misdemeanor, court must revoke at least 30 days, up to one year in jail and $2,000); questions use the statute and the 30-day minimum the manual also gives; (3) zero tolerance (PDF p. 20: 'second or subsequent' 180 days) differs from SDCL 32-23-21 (one year for a third or later offense); only first and second offenses are tested; (4) phones (PDF p. 19 lists texting, reading texts and social networking) is narrower than SDCL 32-26-47.1 (any mobile electronic device, Class 2 misdemeanor, exceptions for calls, emergencies, navigation and hands-free use); questions follow the statute; (5) the instruction permit section (PDF p. 8) omits the SDCL 32-12-11 rule that between 10 p.m. and 6 a.m. a parent or guardian must sit beside the holder; a question uses the statute; (6) the restricted permit section (PDF p. 8) omits the SDCL 32-12-12.5 limit of one non-family passenger under 18 after six months; questions use the statute and the DPS teen page; (7) school buses (PDF p. 43 says always stop for red lights) omits SDCL 32-32-6 details (stop at least 15 feet away, amber lights mean 15 mph or less on roads with fewer than two lanes each way, no stop for a bus on the other side of a road with two or more lanes each way); questions use the statute; (8) following distance is a minimum of 4 seconds in the manual (PDF p. 51) but the DPS teen page tip says to teach the three-second rule, so following_seconds uses the manual and is noted; (9) large-truck stopping distance is 290 feet (PDF p. 62) and 335 feet (PDF p. 63), so it is not tested; (10) the 200-foot distance behind snowplows (PDF p. 67) and the 500-foot U-turn sight distance (PDF p. 39) were not found in the statutes read, so they are not tested; (11) the manual is silent on left turn on red, which SDCL 32-28-4.1 leaves to city ordinance for one-way-to-one-way turns; a question uses the statute. Fees (PDF p. 7), points (PDF p. 14), window tint (PDF p. 24) and move-over (PDF p. 2) match the statutes. edition) and from official sources on road signs.
